BENT-WOOD TANK.

Specification of Letters Patent. I

Patented March 23, 1909.

Application filed February 28, 19.08; Serial No. 418,380.

To all whom it may concern: Be it known that I, STEPHEN O. MACK, citizen of the United States, residing at Trenton, in the county of Mercer and State of New Jersey, have invented certain new and. useful Improvements in Bent-Wood Tanks, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to an improvement in tanks, and relates particularly to bent- Wood tanks.

The object of this invention is the provision of means for forming a portion of the body of the tank, by folding or bending a flexiblesheet carrying sections of the tank.

Another object of this invention is the production of a tank which is comparatively simple and inexpensive to construct, and will positively prevent any leakage at the engaging ends of the front and end sections.

With these and other objects in view, the

" invention consists of certain other novel constructions, combinations, and arrangements of parts, as will be hereinafter fully described and claimed.

In the drawings: Figure 1 is a rear elevation of the tank constructed in accordance with this invention. Fig. 2 is an end elevation of the tank constructed in accordance withthe present invention. Fig. 3 is a top view of the front and end sections connected to a sheet or strip of flexible material. Fi 4 is a top plan view of the body of the tank.

Referring to the drawings by numerals, 1 designates the bottom of the tank, upon which is mounted a body portion, secured thereto by any suitable fastening means. The body comprises a back 2 secured to the narrowest ends of sections 3 by any suitable fastening means, as is indicated by dotted lines 4, Fig. 4. Two end sections or portions 3 interlock at their front ends, withthe ends of the front section or portion 5. These sections or portions 5 and 3 respectively are secured to a strip of flexible wood, or other material 6, as for instance, veneer, by glue or other adhesive material, constituting fastening means.

Any suitable molding 7 may be secured to the sides of the body of the tank, and a top 8 is placed upon the body, and, while it is shown as detachable, it may be fixedly secured to the body by any suitable fastening means.

The outer faces of the front or end sections or portions are rounded on their outer faces as at 9 and 10, respectively, contiguous to their engaging ends. It is to be noted that, owing to the sections or portions being spaced apart upon the sheet or strip 6, by reason of this curving or rounding of the portions 9 and 10, the same can be folded together, positively causing the fastening means to interlock, as illustrated in Fig. 4. By folding the sections 3 at right-angles to the front section 5, the tongue or projecting portion 11 will be seated in the groove or recess portion 12, allowing the shoulders 13 and 14 and sections 3 and 5 to fit snugly against the flat portions 14 upon 0 posite sides of the recesses or grooves 12, l5ig. 4. The tongues 11 and the recess ortions 12 are positioned at an angle to t e sides of the front end-portions or sections of the body, so that they will interlock, Fig. 4,

when the sheet is folded for placing the endsections at right-angles to the front section. It is to be noted that the end-sections or portions 3 are notched or cut-out at '15 for producing the narrow end-portions of said sections which overlap the ends of the rear portion or section 2. liar construction of the tongue and groovestructure and the beveling or rounding of the contiguous ends of the sections upon their outer faces, providing a very sim le interlocking means for fixedly securing t e contiguous ends of the front section together, and also forms a tight joint.

It will be obvious that I have produced a very simple and eflicient tank, as the parts can be quickly folded after assembling upon the flexible sheet or strip of veneer. Furthermore, the top, bottom, back, etc., of the tank can be separated for shipment or transportation, and, owing to the structure, the work of assembling the parts will be greatly facilitated over an ordinary tank. I

The inner face of the veneer strip 6 may be steamed between the contiguous ends of the sections to facilitate the bending of the same.

What I claim is:

As an improved article of manufacture, a bentwood tank, comprising a bod said body comprising a back, a single s eet or strip of flexible material provided with front and similarly constructed end sections, said front and end sections being fixedly secured to said sheet, said sheet extending the entire length of the front and end sections, said The pecuend sections each provided, atitsouter end; With a shoulder and with an integral extension 1projecting beyond the: shoulder and: paral e1 with the sheet, and each end section is provided upon its inner face, at the-inner end, With a curved portion, said inner end being formedat an angle to the inner and outer faces of the section and rovided with, a tenon having straight paral e1 sides, said front section provided upon its inner face, nearits ends, with curved. portions and the endsof'saidfront-section being f ormed at an angle to the front andlback faces of-saidsections, and each end provided with a recess having straight farallel' sides adapted to engage the similar -eonstructed sides of the contiguous tenon' when the sheet is folded forclosingthe inner ends of the ondsection upon the ends of the front section, said shoulders of the end sections fitting against the inner face of the back section and the extensions contiguous to said shoulders cov- 'ering the entire ends of the back section, an d having means extending through the exten- STEPHEN.
